Simulation and Analysis of Physical Mechanisms Related to Unsteady Pressure Fluctuations in Gas Turbine Testing Facilities

Large test cells are used to evaluate the performance of modern jet engines. MDS Aero Support Corporation is a leading designer and manufacturer of these test cells. In a large engine test cell, it is common to experience large amplitude, low frequency unsteady pressure fluctuations at various sections of the facility. If not treated properly, they can be detrimental to the facility and engine testing. Work is currently underway to determine how exactly the flow in the test cell gives rise to the unsteady pressure fluctuations by studying the underlying physical processes at play. In the present project in collaboration with Dr. Jeff Defoe at the University of Windsor, that insight will be applied to develop design changes expected to reduce the pressure fluctuations. These will then be assessed using high fidelity numerical simulations of the air flow in the test cell.
